REGINALD BAXTER, OF LONDON, ENGLAND.

MEANS FOR APPLYING MEDICAMENTS TO THE BODY.

Application filed July 19,

7 To all whom it may concern Be it known that I, REGINALD BAXTER, a subject of the King of Great Britain and Ireland, and a resident of London, county of London, England, have invented a certain new and useful Improvement in Means for Applying Medicaments to the Body, of which the following is a specification.

My invention, which relates to appliances or means for applying medicaments, other than liquids or fluids, to the body, is directed to the syringe-like kind of appliance comprising a cylinder provided with a plunger or piston and rod thereto, said piston, to which a slight movement can be imparted to express the medicament and which fits in the open end of the cylinder, being formed with a flat concave saucer section on its acting face to receive a correspondingly shaped medicament.

My invention has for its object the provision of an improved construction of an appliance ormeans of the above nature as hereinafter described, pointed out in the appended claims, and illustrated by the accompanying sheet of drawings, wherein Figure 1 is an external View; and,

Fig. 2 a sectional view of the appliance constructed in accordance with my invention.

According to my invention, theappliance consists of a stem a, preferably, but not necessarily so, circular, and of metal, vulcanite, rubber, glass, or other suitable material. The stem at is bored out centrally or made hollow so as to receive the rod 1) of a piston or plunger 0 which fits tightly in a cylindrical portion (Z at one end of the stem a. The rod 6 projects from the other end of the stem a and is provided with a press-button or head 0 having checks, stops or collars f to limit the movement of the plunger or piston, by engaging with one or the other end of a two-part split plug of metal or other material 9 which tightly fits and closes the inner end of the stem 64.

The outer end of the stem at is provided with a round, bulbous, pear, ball or other shaped head it in which is formed the cylindrical portion 03 in which the piston or Specification of Letters Patent. Patented Se t. 28 1920.

1920. Serial No. 397,332.

plunger 0 fits, and forms, when said piston or plunger 0 is drawn back, a cavity for the reception of a medicament, such as medicated cream or the like, which, when the appliance is in use and in position, is expressed from the. cavity by the forward movement of the piston or plunger 0.

The head of the piston or plunger is rounded or curved so as to fully express the medicament from the cavity, and to complete the curved surface of the head it of the stem, which head it is provided with a series of exterior and peripheral grooves i to assist in distributing and spreading the medicament over the part under treatment.

The inner end of the stem at is left open, so that the piston 0, its rod Z), and the plug 9 can be readily withdrawn allowing of the easy cleaning of the parts of the apparatus.

Although the above described and shown arrangement of appliances is to be preferred, yet thesame may be varied, so long as they permit of the ready withdrawal of the parts.

I claim 1. Means for applying medicaments, other than liquids or fluids, to the body, characterized by a hollow stem with a rounded or bulbous-shaped head thereto, a series of peripheral grooves on the exterior of said head, an inwardly turned cylindrical portion or tube in said head, and a piston with rounded or curved head slidable within said cylindrical portion or tube, said rounded or curved head, when the medicament is fully expressed, completing the rounded or bulbous head of the stem.

2. Means for applying medicaments other than fluids or liquids to the body including a hollow stem having a head provided with an inwardly turned cylindrical portion, a piston in said cylindrical portion, a removable closure for the end of the stem opposite the head, and a piston rod passing through said closure provided with checks or stops to engage the same.

In testimony whereof I have afiixed my signature hereto this first day of July, 1920.

REGINALD BAXTER, M. D.
